CALIBRATION
(cant)
The following operations generate new frequency calibration constants, regardless
of calibration measurement disable:
-CAL FREQ (BLUE shift PRESET) (does not enable calibration measurements)
(does not enable calibration measurements)
Note: The BLUE shifted function of the PRESET key is not marked on the front
panel. Sweep and ARB must be also be OFF.
Calibration Disable, E04
The CAL OFF (BLUE shift STO) key or the "CD" command from the HP-1B,
disables all amplitude and frequency calibration maasurements. While calibration
measurements are disabled, the 3314A will use the calibration constants previous-
ly computed and display
E04" (Calibration Not Performed). Since a complete
calibration is
only calibration type that generates all 29 constants, it is impor-
tant to do a CAL ALL (BLUE shift RCL) or "CA", prior to calibration disable and at
regular intervals there after. A CAL ALL should be performed every 24 hours or
whenever the temperature changes more than 5°C.
The primary advantage for using calibration disable is the time saved when
operating via the HP-IB. Note, when operating via the HP-IB with calibration disabl-
ed, set Display Errors OFF" DEO". If Display Errors is ON, E04
will
be displayed
for 1/2 second every time a calibration measurement is not performed. During the
time E04 is displayed, all 3314A HP-IB functions are halted.
Calibration Enable
Power ON, the PRESET key,
HP-IB command, the CAL ALL (BLUE shift RCl)
key and the
command, enable amplitude and frequency calibration
measurements. All of these operations cause the execution of a complete calibra-
tion, except'" CE" .
